BACKGROUND

The present invention relates to a construction element for heatinsulation between two building parts, in particular between a ceilingor wall and a construction part protruding from said building, such as abalcony, at least comprising an insulating body and reinforcementelements crossing said insulating body and connected to each of the twoconstruction parts, with tensile reinforcement elements being providedas reinforcement elements, at least arranged in an upper area andprotruding particularly horizontally in reference to the insulating bodyand compression elements being provided arranged in the lower area ofthis insulating body.

In certain regions, construction elements for heat insulation aresubject to strict regulations with regard to earthquake safety; here,the sufficiently known construction elements for heat insulation must beable to absorb additional dynamic stress, which requirement previouslyhas been largely neglected and/or was not focused on. For example, ifthe construction element for heat insulation serves to supportprotruding balcony plates and is designed such that it can support itsown weight and can absorb forces and momentums affecting the balconyplate from the outside, now forces and momentums acting in the oppositedirection are added, for example such that the construction partsadjacent to the construction element are accelerated to a differentdegree by the vibrations of an earthquake and can be pulled apart, forexample; or the protruding construction part is subjected to a force ormomentum component acting vertically upward against the effectivedirection of the weight as a result of a tipping motion, whichconventionally used compression rods in the lower insulating area andtensile rods in the upper insulating area cannot withstand alone.

Although it would be possible in an easy manner to drastically increasethe number of reinforcement elements in the construction element forheat insulation and to arrange them at different positions so that eachposition affected by a force or momentum is provided with an appropriatereinforcement element; however, this would not only drastically increasethe material expenses of such a construction element but also the heatinsulation features would considerably worsen by the respectivelyenlarged cross-sectional area of the reinforcement elements extendingbetween the two adjacent construction parts.

SUMMARY

Therefore, the present invention is based on the object of providing aconstruction element for heat insulation of the type mentioned at theoutset, which allows a targeted and only partially implemented increaseof the number of reinforcement elements using conventional parts, andthus to avoid, on the one hand, a static and dynamic oversizing of thereinforcement elements and, on the other hand, an enlargement of thecross-sectional area of the reinforcement elements extending between thetwo adjacent construction parts compromising the heat insulationfeatures.

The objective is attained according to the invention in thathorizontally adjacent to the insulating body at least one additionalinsulating body is arranged, aligned therewith, that the additionalinsulating body in the area of its lower half is provided withadditional tensile reinforcement elements for earthquake stress, whichprotrude in the horizontal direction in reference to the insulatingbody. By combining a conventional construction element for heatinsulation with another insulating body equipped for earthquake stress,which is merely provided with additional tensile reinforcement elementsin the lower part of the insulating body, the following advantagesdevelop, in particular: the conventional construction elements for heatinsulation are used, as in the past, to compensate for the normal staticand dynamic stress; therefore, the additional insulating bodies, alignedadjacent therewith, have no influence on the size and composition ofconventional construction elements for heat insulation, whichfacilitates the planning, sizing, and implementation of the combinedconstruction element for heat insulation.

The aligned adjacent additional insulating body only needs theadditional tensile reinforcement elements mentioned in order to allowthe compensation of tensile forces developing during earthquakes in thelower area of the insulating body, which can not be compensated and/ortransferred by the compression elements and lateral reinforcement rodsconventionally present in this plane. Advantageously, the tensilereinforcement elements arranged in the conventional insulating body alsoact in case of an earthquake for transferring forces into the area ofthe upper half of the insulating body and/or for transferring lateralforces. Thus, except for the additional tensile force elements theadditional insulating body needs no additional other reinforcementelements. Thus, it is apparent that the attached additional insulatingbody with the additional tensile reinforcement elements alone cannotprovide and/or ensure sufficient function, neither for earthquake stressnor for normal stress, and that only together with the adjacentconventional construction elements for heat insulation can it fulfillits assigned tasks.

With regard to the additional tensile reinforcement element, it isusefully embodied in a rod-shaped manner known per se and protrudesbeyond the additional insulating body in order to extend far into theadjacent construction parts and be appropriately well anchored in them.

The additional tensile elements may furthermore be provided, at least atthe face end, with a plate-shaped force transfer profile, which extendsparticularly in a generally vertical plane parallel to the plane of theinsulating body. This way, the necessary force introduction area isconsiderably shortened, which for example is advantageous whenadditional constructive parts, such as supports etc. are provided in themounting area of the additional tensile reinforcement elements, intowhich the additional tensile reinforcement elements may not extend.

Therefore, the additional insulating body is provided with twoadditional tensile reinforcement elements arranged at a horizontaldistance apart from each other. Thus, the additional insulating body isonly provided with two additional tensile reinforcement elements,however, it is sufficiently sized to fulfill its intended tasks.

Horizontally adjacent to the additional insulating body, a secondinsulating body aligned thereto with integrated tensile and pressurereinforcement elements is arranged so that a constant row ofconventional construction elements for heat insulation is onlyinterrupted by a short section of an additional insulating body withonly two additional tensile reinforcement elements, in particular.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A construction element for heat insulation 1 according to the inventionis shown in FIG. 1, which comprises a combination of two conventionalconstruction elements for heat insulation 2 with a construction elementfor heat insulation 3 designed for earthquake stress. The conventionalconstruction elements 2 are provided with an insulating body 12 as wellas reinforcement elements allocated to the insulating body 12, and whichextend through it in a plane essentially perpendicular to itslongitudinal extension, and only partially protruding in reference tothe insulating body 12. In the exemplary embodiment of FIG. 1, in theconventional construction elements 2, upper reinforcement tensile rods 4extending in the horizontal direction are provided as reinforcementelements, as are lower compression supports 5, ending approximatelyflush with the insulating body, as well as lateral reinforcement rods 6extending diagonally from the top downwards through the insulating bodyand being bent outside said insulating body in a horizontal direction.These conventional reinforcement elements, as discernible in FIG. 1, arearranged according to a grid, predetermined and adjusted and/oradjustable to the respective stress. The insulating body of such aconstruction element for heat insulation 2 is generally divided in thehorizontal direction in the area of the reinforcement elements in orderto facilitate the assembly and/or positioning of the reinforcementelements.

Another insulating body 14 is arranged between the two conventionalconstruction elements for heat insulation 2, extending in the verticalplane of the adjacent insulating body 12 flush thereto and beingprovided with tensile reinforcement elements 15 extending only in thelower area of the insulating body for compensating for earthquakestress, which extend parallel to the tensile reinforcement rods 4 of theconventional construction elements 2 but at a lower height plane.

FIG. 2 shows in a schematic front views parts of the conventionalconstruction elements for heat insulation 2 as well as the additionalinsulating bodies 14 inserted therebetween having the additional tensilereinforcement elements 15, with the additional insulating body and theadditional insulating elements forming the construction element for heatinsulation particularly embodied for earthquake stress.

From FIG. 2 it is discernible how, adjacent to this construction elementfor earthquake stress, the reinforcement elements are provided in formof tensile reinforcement rods 4, lateral reinforcement rods 5, andcompression elements 5. While the compression elements 5 accept no oralmost no other functions for the particular additional earthquakestress, in particular the tensile reinforcement elements 4 serve tocompensate the compression and lateral force components developingduring earthquakes. This is limited, at least according to calculations,to the tensile reinforcement rods arranged adjacent to this constructionelement for earthquake stress 3.

As shown in FIGS. 3 and 4, a plate-shaped force introduction profile 16can be connected to or provided on the ends of the tensile reinforcementelements 15 of the construction elements for heat insulation 2. Theplate-shaped force introduction profile 16 extends in a generallyvertical plane, parallel to the additional insulating body 14. Theplate-shaped force transfer profile 16 considerably shortens thenecessary force introduction area. This is particularly advantageouswhen additional constructive parts, such as supports etc. are providedin the mounting area of the additional tensile reinforcement elements15, into which the additional tensile reinforcement elements 15 may notextend.

It is easily discernible that both the calculation and sizing is veryeasy when the construction elements for earthquake stress are notchanged in their design in reference to conventional constructionelements for heat insulation and that the assembly and/or implementationof these construction elements for earthquake stress can occur veryeasily such that after the assembly and/or implementation of theconventional construction elements for heat insulation a constructionelement for earthquake stress is added.

In summary, this results in the advantage that by simple means and aminimum of material, conventional construction elements for heatinsulation can be retrofitted and/or complemented such that they aredesigned for earthquake stress, with the reinforcement elementsaccording to the invention for conventional construction elements acceptfunctions for earthquake stress which per se were to be accepted by theconstruction element, but which can, at least according to calculations,easily be distributed to the adjacent reinforcement elements of theconventional construction elements.
